    • This invention concerns a discrete carbon fibril characterized by a substantially constant diameter between about 3.5 and about 70 nanometers, length greater than about 5 times the diameter and less than about 100 times the diameter, an outer region of multiple essentially continuous layers of ordered carbon atoms and a distinct inner core region. The invention further concerns a plurality of such fibrils.The fibrils of this invention may be produced by contacting for an appropriate period of time and at a suitable pressure a suitable metal-containing particle with a suitable gaseous, carbon-containing compound, at a temperature between about 850.degree. C. and 1200.degree. C., or by treating discrete carbon fibrils, characterized by a length greater than about 100 times the diameter. Carbon fibrils may also be continuously produced by continuously contacting for an appropriate period of time at suitable conditions.Another aspect of the invention concerns a composition of matter comprising a carbon fiber or a carbon plate and a plurality of fibrils.Carbon fibrils and compositions of matter comprising carbon fibrils are useful in composites having a matrix of e.g., an organic polymer, an organic polymer or a metal. In specific embodiments, the fibrils or the compositions of matter may be used to reinforce a structural material, to enhance the electrical or thermal conductivity of a material, to increase the surface area of an electrode or capacitor plate, to provide a support for a catalyst, or to shield an object from electromagnetic radiation.

    • A method for the decontamination of a soil, sediment, or sludge containing toxic halogenated organic compound and containing water comprising the steps of mixing said soil, sediment, or sludge with a reagent capable of reacting with said halogenated compound and heating said mixture of soil, sediment, or sludge, and reagent in a reaction zone to an elevated temperature thereby forming a reaction zone vapor stream containing at least a portion of the water contained in said soil, sediment, or sludge and unreacted halogenated organic compound; condensing a portion of said reaction zone vapor stream under conditions suitable for the formation of a condensate stream containing substantially all of the halogenated organic compound in said reaction zone vapor stream, and a vapor stream containing water and trace amounts of said halogenated organic compound; recycling said condensate to said reaction zone; treating said vapor stream to remove trace halogenated organic compound and venting the so-treated stream to the atmosphere; and removing soil, sediment, or sludge containing less contaminant from said reaction zone.
